Abstract
An implantable device includes a conduit, an adjustable membrane element coupled to the conduit near the front end of the conduit for controllable coaptation of a body lumen, such as coaptation of a urethra as treatment for urinary incontinence, and a fixation mechanism at or near the front end of the conduit. In various embodiments, the fixation mechanism can anchor the implantable device to the tissue using a movement of a push wire. Optionally, the fixation mechanism can also allow the implantable device to be released from the tissue using another movement of the push wire, to allow for repositioning or removal of the implantable device.
Claims21
(canceled)
An implantable device configured to be positioned in tissue of a living body using a push wire for coaptation of a body lumen of the living body, the implantable device comprising:
- an adjustable membrane element including a continuous wall having an inner surface defining a chamber;
- an elongate conduit including a conduit peripheral surface, a conduit rear end, a conduit front end, and one or more lumens extending longitudinally in the elongate conduit, the conduit peripheral surface connected to and sealed to the adjustable membrane element at or near the conduit front end, the one or more lumens including an inflation lumen including a rear opening at the conduit rear end, a front opening in fluid communication with the chamber of the adjustable membrane element for adjusting the adjustable membrane element using a flowable material introduced through the rear opening;
- and
- a fixation mechanism including a base positioned in a lumen of the one or more lumens at the conduit front end and a helix coupled to the base, the helix configured to be rotated with the base to enter the tissue to anchor the implantable device to the tissue,
- wherein the implantable device is configured for implantation within the tissue with the adjustable membrane element adjacent the body lumen to provide volume to the tissue for adjustable coaptation to the body lumen.
A method for coapting a body lumen of a living body, the method comprising:
- providing volume to tissue adjacent the body lumen using an implantable device including:
- an adjustable membrane element including a continuous wall having an inner surface defining a chamber;
- an elongate conduit including a conduit peripheral surface, a conduit rear end, a conduit front end, and one or more lumens extending longitudinally in the elongate conduit, the conduit peripheral surface connected to and sealed to the adjustable membrane clement at or near the conduit front end, the one or more lumens including an inflation lumen including a rear opening at the conduit rear end, a front opening in fluid communication with the chamber of the adjustable membrane element for adjusting the adjustable membrane element using a flowable material introduced through the rear opening;
- and
- a fixation mechanism configured to anchor the implantable device to the tissue, the fixation mechanism including a base positioned in a lumen of the one or more lumens at the conduit front end and a helix coupled to the base;
- and
- anchoring the implantable device to the tissue using the helix, the helix rotated with the base to enter the tissue,
- wherein the implantable device is configured for implantation within the tissue with the adjustable membrane element positioned adjacent the body lumen.
